Research Abstract

Noscapine is clinically available safe medicine, and antitumor action is found in MDR-overexpressing cancer. Because it was considered that MDR overexpression was involved in drug resistance of the renal carcinoma, we added Noscapine to renal carcinoma cells ACHN and confirmed antitumor effect in in vitro and in vivo. We confirmed antitumor effect in the prostate cancer cell line. Noscapine inhibited the proliferation of not only androgen-independent prostate caner cells DU145 but also DU145-TxR which is resistant for paclitaxel and docetaxel.DU145-TxR overexpressed MDR mRNA and p-glycoprotein that stimulate.
For the purpose of expecting a synergistic effect with noscapine and flavonoids in prostate cancer, we investigated the effect of flavonoids on the androgen responsiveness. After LNCaP cells were transfected with PSA promoter-driven Luciferase reporter, cells were treated with DHT with flavonoids. Then naringenin showed the strong suppression of androgen responsiveness.
